How should the microphone gain control be adjusted for voice operation on a single-sideband transmitter?

Adjusting the microphone gain properly is critical in Single Sideband (SSB) operation to ensure a clean, understandable signal. The gain controls the audio level fed into the transmitter's modulation circuits. To set it correctly, you should monitor the Automatic Level Control (ALC) meter and ensure that voice peaks never exceed the manufacturer's recommended maximum range. If the microphone gain is set too high, the transmitter's final amplifier gets overdriven on voice peaks. This causes severe distortion, often referred to as 'splatter,' which widens your transmitted signal and interferes with adjacent frequencies. Common distractors on this question refer to other modes or older equipment. '100% frequency deviation' applies exclusively to FM transmitters, not SSB. Tuning for a 'dip in drain or collector current' is a procedure used to tune the final RF amplifier stages of older tube transmitters, having nothing to do with microphone audio gain.
